Autism

            
             Autism is a neurological disorder that affects functioning, particularly in communication and social skills. Bodily impairments, abnormal movements, and sensory dysfunctions characterize autism. .
             Although no known cure for autism exists today, doctors and scientists are exploring ways to help eliminate the causes. Researchers all over the world are linking autism to abnormal genetics, unreliable vaccines, mercury poisoning, and many other causes. Many researchers, doctors, and scientists conclude that autism is most likely a combination of many genetic and environmental factors. The number of cases of autism syndromes has risen over 900% in the past decade, and the condition now affects one in every 500 children. The following are some of the newest theories/causes of autism:.
             Mercury poisoning, when detected, is often initially diagnosed as a psychiatric disorder with symptoms such as poor eye contact, irrational fears, aggressive behavior, temper tantrums, irritability, and mood changes. Exposure to mercury can cause immune, sensory, neurological, motor, and behavioral problems similar to traits associated with autism and similarities that extend to neuroanatomy and biochemistry. Many cases of idiopathic autism may be induced by early mercury exposure from thimerosal, a preservative added to many vaccines. Children may be exposed to excessive mercury levels at a young age and have lifelong symptoms. In the developing brain, mercury interferes with neuronal migration, depresses cell division and disrupts normal functions. A characteristic of mercury poisoning is the variability it affects the individual, so that at the same exposure level some will be affected severely while others will not at all. Autism is more prevalent among boys than girls with a ratio of 4:1. Although at high doses both sexes are affected equally, males are most prone to being affected by low doses. In most affected children, autistic syndromes emerge gradually with the first symptoms being sensory and motor-related, followed by speech and hearing deficits.
